At a former job, we had a religious flamewar around the pronunciation of GIF. I argued that the G should be a hard-G because it represents the word Graphics. My colleagues argued that since the G is in front of an I, it should be a soft-G as in giraffe. They further argued that the creator of the format pronounces with a soft-G so we should take that as the final proof.

So, at that job, I was the author of our Output Run-Time module, abbreviated ORT. As the creator, I demanded that it be pronounced GIF with a hard-G. Some people hated me.
